AbstractÃ‚Â Ã‚Â Mycelia Sterilia YY-5, an endophytic fungus isolated from Rhus Chinensis Mill, was used in SSF for laccase production using steam-exploded wheat straw (SEWS). The fermentation period of YY-5 in solid state fermentation (SSF) shortened to 4Ã‚Â days compared with...

An alkalophilic bacterium Bacillus cereus produced an extracellular alkaline protease, which was found to be very active at high temperature and pH range. The enzyme showed high compatibility with commercial laundry detergents. The production of the alkaline protease in aqueous two-phase system...

Anaerobic xylulose fermentation was compared in strains of Zygosaccharomyces and Saccharomyces cerevisiae, mutants and wild-type strains to identify host-strain background and genetic modifications beneficial to xylose fermentation. Overexpression of the gene (XKS1) for the pentose phosphate...

Enantiomerically pure, fluorinated compounds have an important role in medicinal chemistry. Alternaria alternata isolates were used for the synthesis of (S)-2â€²-fluorophenylethan-1-oI 1b and (S)-3â€²-fluorophenylethan-1-ol 2b. Biocatalytic syntheses of optically active 1b and 2b were...

Presents the results of membrane and ozonation experiments carried out on various agro-industry effluents including fermentation, corrugated board, opium alkaloid and textile dying industries. How the experiments were performed using lab-scale membrane and ozonation reactors; Findings that the...

In the paper are presented the results of the sensory properties of "levacka" sausage, manufactured in a traditional way of production. Simultaneously, colour and firmness of the sausages were determined instrumentally. Sausages were produced in three intervals: September (the first fermentation...

In recombinant Pichia pastoris fermentation for hirudin production in a 5 l fermenter, a new strategy was explored to match the short fermentation time at low NH4+ concentration with decreased hirudin degradation at high NH4+ concentration. A combination of a defined medium containing initial...

In high gravity Saccharomyces cerevisiae fermentations containing 300 g glucose l-1, daily addition of acetaldehyde to a total of 93 mM shortened the time required to ferment the first 250 g glucose l-1 from 790 h to 585 h. Acetaldehyde feeding had no effect on the ethanol yield but increased by...
